Chapter 2 Test Review
Directions: Below are questions that will help you prepare for the Chapter 2 Test. There will be a calculator part and a noncalculator part for the test. Try to complete the exercises without a calculator where it states “No Graphing Calculator.”
Section 2.1 – Quadratic Functions (No Graphing Calculator)
1. Find the vertex, axis of symmetry, x-intercepts, and y-intercepts and then sketch a graph of
f (x)  2x 2  12x 16

2. Among all possible inputs for the function g(x)  3x 2 12x  6 which yields the smallest output? What is this
minimum output?
